Application filed May 20, 1918. Serial No. 285,716.

To all whom it may concern:

Be it known that I, WILLIAM H. Rown, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented. new and useful Improvements in Acetylene-Generators, of which the following is a specification.

My invention relates to an acetylenergenerator and consists of the novel features herein shown, described and claimed.

One of the principal objects of my invention is to make a gas operated motor for feeding the carbid and to regulate the motor automatically by the gas pressure.

, Figure 1 is atop plan view of an acetylene generator embodying the principles of my invention looking in the direction indicated by the arrow 1 in Fig. 2.

Fig. 2 is a side elevation looking in the direction indicated by the arrow 2 in Fig. 1.

Fig. 3 is a fragmentary vertical central section of the gas controlswitch for reguilating the motor taken on the line 3-3 of Fig. 4 is a vertical section of the motor taken on the line 4-4 of Fig. 2.

Fig. 5 is a fragmentary vertical sectional detail taken on the lines 55 of Figs. 1 and 2.

Fig. 6 is a horizontal sectional detail taken on the line 66 of Fig. 5.

A generating tank 1 is circular in plan and has a dished bottom 2 provided with a drain pipe 3 leading from its lowest point, the flow through the pipe being controlled by a stopcock 4. A rim 5 extends downwardly in line with the wall of the tank 1 to hold the bottom 2 elevated. An agitator 6 is mounted horizontally in the tank 1 to be operated by a crank 7. The agitator 6 consists of a shaft 8, arms 9 extending from the ends of the shaft and blades 10 connecting the arms; said blades 10 being curved on their outer faces to fit closely the inner face of the bottom 2. r

A filling funnel 11 is connected to a pipe 12 which extends downwardly from the bottom of the funnel and then laterally through the wall of the tank 1 at its upper end, there being a stop cock 13 to control the passage through the pipe 12 so that by opening the stop cook 13 water may be poured into the funnel 11 to fill the tank 1 to the desired extent.

A gas dome '14 extends upwardly from the tank 1 and is built upon the tank 1, there being a flanged wall 15 connecting the lower edge of the vertical wall of the dome 14 to the upper edge of the vertical'wall of the tank 1, so as to make the dome considerably smaller in plan than the tank. A pressure gage 16 is tapped into the dome 14 at one side, a safety valve 17 is connected through the wall of the gas dome 14 near the top of a gas chamber 18, said safety valve being provided with a cap 19 held in place by a padlock 20 so that the valve can not be tampered with without removing the padlock. A pipe 21 connects the valve casing to the chamber 18 through the wall 14, and a pipe 22 extends downwardly from the valve casing to a T 23. A U-shaped trap 24 extends downwardly and upwardly from the T 23,

a blow-01f pipe 25 extends upwardly from a T 26; said T 26 being on the opposite end of the trap 24' from the T 23. A pipe 27 connects the T 23 to a chamber 28 within the tank 1, the passage through the pipe 27 being controlled by a stop cook 29 and a. di rai6n pipe 30 leads horizontally from the When it is desired to clean out the tank 1 and start the generator to operating, the stop cock 4 is opened and the stop cock 13 is opened, water poured'into the funnel 11 ,and allowed to run into the tank 1 and the blow-0E pipe 25 or the drain pipe 30, until the surplus pressure has been reduced. A cap plate 31 is bolted to an anfigile flange 32 and the angle flange is rigidly ed upon the upper end of the as dome 14. Before the cap plate 31 is apied, a carbid hopper 33 is centrally located within the vertical wall of the gas dome 14; said hopper having a flange 34 extending outwardly around its upper edge to rest upon the upper edge of the dome 14. A man hole construction 35 rovides access to the hopper 33 for inserting the carbid 36. A feed plate 37 is horithe pipe 22, through the trap 24 and through zontally suspended below the hopper 33 by straps 38; said feed plate being circular in, plan and located a short distance below the outlet 39 of the hopper. A feed shaft 40 is mounted vertically through the center of the cap plate 31, there beino a stutiing box construction 42 around tie shaft and the lower end of the feed-shaft 40 is rota taoly mounted through the center of the feed plate 37, there being blades 43 and 44 fixed upon the shaft 40 and swinging upon the upper face of the feed plate 37, so that when the shaft 40 rotates the blades 43 and let will swing to move the carbid outwardly and discharge it upon the periphery of the feed plate 37. The front faces of the blades -13 and ist are winding backwardly relative to a radial line so as to continuously advance the carbid toward the rim of the feed plate by the rotation of the blades.

A worm gear 45 is fixed upon the upper end of the shaft 40 above the cap plate 31, a shaft 46 is mounted in bearings 47 on top of the cap plate 31 and carries a worm 48 in mesh with the gear 45. The shaft 46 extends heyond the edge of the cap plate 31 and a pulley i9 is lined upon the outer end of the shaft. A belt 50 connects the pulley 49 to a pulley 51 fixed upon a shaft 52 of a gas motor 53, a pipe 54 leads outwardly from the upper part of the chamber 18 through the dome l4- and an automatic switch, is connected to this pipe 54. A pipe 58 connects the automatic switch 55 to the dead side of the motor 53 and a pipe 57 connects the switch 55 to the live side of the gas motor 53.

Referring to Fig. 3 the automatic switch comprises a casing 58 having a lower chamber 59, a by-pass 60, an upper chamber 81 a lower pocket 62, upper pocket 63, a valve seat 64 leading from the lower chamber 59 to the lower pocket 62, and a valve seat 65 leading from the upper chamber 81 to the upper pocket 63 the pipe 557 communicates with the pocket 62 and. the pipe 56 communicates with the upper pocket 83. A diaphragm 86 is mounted against the upper end of the casing to cover the chamber 61, a cap 87 is screwed down upon the casing 58 to hold the diaphragm 86 in place, a spring casing 68 extends upwardly from the cap 87, a spring 89 is placed in the casing 68 against the diaphragm 66, a follower 70 is placed against the upper end of the spring 69, a wall 71 closes the upper end or the spring casing, a set screw 72 is screw seated through the wall 71 against the follower 70 to regulate the tension of the spring 69 and a cap 73 is hinged in place to cover the set screw 7:2 and held loy a padlock 7%. A valve stem 7 is connected to the diaphragm 88 and extends downwardly through the valve seat '65. through partition 78hetween the lower pocket 82 and the upper i ase vee pocket 83 and through the valve seat 6%.. A valve 77 is fixed upon the valve stem 75 in position to engage the valve seat 64, and a valve 78 is fixed upon the valve stem 75 in position. to engage the valve seat 64; valves 77 and 78 being located so that when the valve 77 is closed the valve 78 is open, and when the valve 78 is closed the valve 77 is open. The tension of the spring 69 is exerted to hold the valve 77 normally closed so that the gas will flow from the gas chamber 18 through the pipe 54, through the valve seat 64 through the lower pocket 62 and through the pipe 57 to the live side of the gas motor 53 as required to operate the motor to feed carbid to the generator, and when the gas pressure goes up the pressure will be communicated through the by-pass 60 and the upper chamber 61 to the diaphragm 66 and raise the diaphra to open the valve 77 and close the valve 8 thereby shutting ed the flow oi. gas through the pipe 57 and stopping the motor, and then the gas will flow through the valve seat 65 and the upper pocket 63 and pipe 56 to the dead side of the gas motor 53.

Referring to Fig. 4. valves 77 and 78 are incorporated into the pipes 57 and 56. A motor casing 79 has a circular chamber 80 and the shaft 52 is mounted concentric to this chamber, a drum 81 is fixed upon the shaft in the chamber and winding blades 82 extend from the periphery of the drum to near the inner face of the motor casing 7 9. A gas dome 83 extends upwardly from the motor casing 78 and a feed pipe 84 leads from the gas dome 83; there losing a stop cook 85 in the feed pipe; a filling nipple 86 is tapped into the casing 79, a stop cook 87 is lined upon the nipple and a funnel 88 is screwed into the stop cock so that hy opening the stop cool: 87 water may he poured through the funnel 88 to casing 89 to the desired extent The valves 77 and 78 hold the water in the casing the gas passing through the pine 57 into. the chamber 86 will pass upwardly through no water against the hooked sides of the lilades 88 and drive the blades to rotate the shaft 52.,

and the shaft 52 carrying the pulley 53 will Y drive the belt 50. the pulley 49, the shaft 48 and rotate the shaft 40 to feed the car oid from the feed plate 37 to the generating tanlr l. The gas will flow from the circular chamber 80 to the gas dome 83 and through the feed pipe 8% to the places of consumption. When the gas pressure in the gas dome 14 from the generator tank 1 goes above the requirements the switch 55 will operate to stop the flow through the pipe 57 and start the low through the pipe 58 and the gas flowing through the pipe will strilre the rounded sides of the blades 82 and pass through the space 88 "between the hlades and the inner face of the casing 79 v nasavee and pass upwardly through the water to the feed pipe without rotating the motor, and this operation will continue until the pressure has gone down to normal, when the switch 55 will again operate to start the circulation through pipe 57 to start the motor and feed more carbld.

Various changes may be made without departing from the spirit of my invention, as claimed.
